- Chemistry
- Bond Polarity
- bonds between the same element are always non-polar
- bonds between the same element may be polar
- electron distribution is not always the symmetrical
- Hydrogen Bonds
- A type of intermolecular force
- only occurs between hydrogen atoms bonded to highly electronegative atom
- can occur between molecules and in the same molecules
- weak in comparison to other IMF
- Bonds
- Covalent
- non metal non metal
- sharing of electrons
- don't conduct electrons
- Drawn as above
- Ionic
- Electrons are donated
- Held together by electrostatic attraction in a lattice
- Drawn in square brackets (as below)
- conduct electricity when dissolved due to free electrons
- metal to non metal
- Metallic
- metal to metal
- conduct electricity due to 'sea of electrons'
- held together by the metal ions attraction to the electrons
- Covalent
- Bond Polarity
